various complications of hydatid cyst have been recognized to date. we have encountered one such complication-rupture of hydatid cyst to the duodenum­ leading to upper gastrointestinal bleeding in a 40 year old male, who referred with severe right upper quadrant (ruq) pain and gastrointestinal bleeding of a few hours' duration. laparotomy revealed a cyst (7 x 15 cm) in the left lobe of the...

conclusions for laterally localized and protruded duodenal diverticula, laparoscopic resection is a feasible and safe method. the role of laparoscopy in surgical treatment of complicated diverticula, located in other parts of the duodenum, is unclear because of lack of experience. case presentation in this article, we present a case report of a large duodenal diverticulum, treated with laparosc...

To investigate the role of acidification in cell proliferation, several cell lines resistant to chloroquine were isolated with the expectation that some would express altered endocytic acidification. The preliminary characterization of one of these lines, CHL60-64, is described. In contrast to endocytic mutants described previously, the initial phase of endocytic acidification, as measured by t...

Uptake of neurotransmitters into synaptic vesicles is driven by the proton gradient established across the vesicle membrane. The acidification of synaptic vesicles, therefore, is a crucial component of vesicle function. Here we present measurements of acidification rate constants from isolated, single synaptic vesicles. Vesicles were purified from mice expressing a fusion protein termed Synapto...

In the United States and other coastal nations, ocean acidification has quickly become a common topic of scientific research. Ocean acidification also has become a public concern as news headlines warn of this potentially threatening byproduct of global climate change. In March 2009, the U.S. Congress passed the Federal Ocean Acidification Research Monitoring Act, a bill to establish an interag...

We present a 69-year-old woman with a duodenal obstruction after successful selective transcatheter arterial embolization (TAE) for a duodenal diverticular hemorrhage. Two weeks after TAE, the patient showed abrupt symptoms of duodenal obstruction. Resolving hematomas after successful selective transcatheter arterial embolization should be thoroughly observed because they might result in duoden...

AIM To investigate the correlation among the presence and degree of gastric metaplasia of duodenal regenerating mucosa, the deformity of bulb and the recurrence of duodenal ulcer. METHODS A total of 99 patients with duodenal ulcer were treated with H(2)-antagonist with or without antimicrobial therapy. All patients received follow-up endoscopic examinations 6 wk after treatment. When the ulce...
